Hex-en with an IUPAC name of 2-(ethylamino)-1-phenylpentan-1-one is a new research chemical. The chemical formula is C13H19NO HCl, the CAS number is 18268-16-1 and it has a molecular mass of 241.76. Since the chemical, NEP is so new we will look at its analogue to learn more which is Mexedrone.

Hex-en is an also new research chemical but some research data is available. The chemical formula for Mexedrone is C12H17NO2 with an IUPAC name of 3-methoxy-2-(methylamino)-1-(4-methylphenyl)propan-1-one a molecular mass of 207.27.

Predicted research on Mexedrone was published by ACD/Labs’ and ChemAxon. In the reports by ACD/Labs, the chemical has 2 hydrogen acceptors, 1 hydrogen donors, 5 freely rotating bonds, an index of refraction of 1.507, with a surface tension of 34.9±3.0 dyne/cm, a flash point of 107.2±22.8 °C and a boiling point of 289.4±23.0 °C at 760 mmHg.

ChemAxon published a topology analysis, which revealed an atom count of 31, bond count of 31, cyclomatic number of 1, chain atom count of 8, chain bond count of 8, asymmetric atom count of 1, and rotatable bond count of 5. Under geometry, the report revealed a dreiding energy equal to 32.55 kcal/mol with a volume equal to 198.73 Å3, a minimal projection area equal to 43.30 Å2 and maximum projection area equal to 57.18 Å2.

Other research showed Mexedrone to have a topological polar surface area of 29.1 A^2, a heavy atom count of 14,
Isotope Atom Count of 0, Defined Atom Stereocenter Count of 0, Undefined Atom Stereocenter Count of 1, Defined Bond Stereocenter Count of 0, Undefined Bond Stereocenter Count of 0, and a Covalently-Bonded Unit Count of 1.

NEH Crystals with a systematic name of 2-(ethylamino)-1-phenylhexan-1-one that is also known hexen and n-ethyl-hexedrone is a research chemical that is in the cathinone group.

NEH Crystals is a compound that is derived from the cathinone group of chemicals. This research chemical was created in the beginning of 2011. The hard work of elucidating the quantitative structure relationship of the activity of the scaffold. The team that created the research chemical searched for the key moieties that ended up creating a compound that performs like a norepinephrine dopamine reuptake inhibitor known as a NDRI that has higher selectivity in transporting dopamine instead of transporting norepinephrine.
NEH Crystals also has shown that this new research chemical has low affinity to transporting serotonin accept for the amount that is actually needed for research and the effect can be skipped completely.
